Prosoco R-Guard Joint & Seam Filler Fiber Reinforced Fill Coat and Seam Treatment 20oz Sausage

Prosoco R-Guard Joint & Seam Filler, Fiber Reinforced Fill Coat and Seam Treatment, 20oz Sausage

PROSOCO R-Guard® Joint & Seam Filler is a gun grade, crack and joint filler, adhesive and detailing compound that combines the best of silicone and polyurethane properties. This single-component, fiber-reinforced, Silyl-Terminated-Polymer (STP) is easy to gun, spread, and tool.

Use Joint & Seam Filler to fill openings and create transitions where flexible reinforcement is required to bridge larger gaps and provide continuous support of fluid-applied flashing membranes, waterproofing or air barrier components.

Suitable for all climates, Joint & Seam Filler bonds directly to damp or dry surfaces and cures under a variety of weather conditions. It dramatically reduces surface preparation time by eliminating the need for reinforcing tapes at sheathing joints, inside and outside corners.

Use Joint & Seam Filler as part of a continuous, building-wide air barrier system, or to prepare surfaces for conventional waterproofing or air barrier components. Joint & Seam Filler may also be used to repair cracks or fill voids after the primary R-Guard air barrier has been applied.

Advantages:

• Streamlines preparation by eliminating the need for joint reinforcing tapes.
• Silane functional polymer provides superior long term adhesion, crack filling and weathering characteristics.
• Bonds to most common building materials without priming.
• Single component saves time – no mixing.
• Bonds and cures in wet weather and on damp substrates. Tolerates rain immediately after application.
• May be fully exposed to UV and weather for up to 12 months depending upon conditions. If longer, contact for inspection.
• Compatible with most sealants and waterproofing or air barrier components.
• Solvent-free. Isocyanate free. Phthalate-free.
• No shrinkage. No staining. No yellowing.
• Breathable – allows damp surfaces to dry.
• Will not support mold growth.
• Passes ASTM E84, Standard Test Method for Surface Burning Characteristics of Building Materials
